The Osprey Katari 1.5 hydration biking backpack is ideal for fast rides that require only the water on your back, letting you carry the bare minimum. The high-quality, low-profile design features an included 1.5-litre reservoir that slides into the exterior pocket with a bite valve that attaches magnetically to a sternum strap. The rolled, soft-edged harness contours to the upper shoulders to keep the pack close to your body and provide stability. This bag is made with mountain bikers in mind, but is appreciated for any activity where hydration is a must.
